Options Trading Basics — Complete Guide
Learn options trading fundamentals: calls, puts, strike prices, expiration, premium, Greeks, and basic options strategies for beginners.
What Are Options?
An option is a contract giving you the RIGHT (but not obligation) to buy or sell an asset at a specific price within a specific time period. You pay a premium for this right.
Key Advantage
Options offer unique benefits no other instrument provides: defined maximum risk, leveraged exposure, ability to profit from time decay, and strategies that profit in ANY market direction (up, down, or sideways).
Call vs. Put Options
| Call Option | Put Option | |
|---|---|---|
| Right | Buy asset at strike price | Sell asset at strike price |
| Buyer Profits | When price goes UP | When price goes DOWN |
| Seller Profits | When price stays below strike | When price stays above strike |
| Max Loss (Buyer) | Premium paid | Premium paid |
| Max Loss (Seller) | Unlimited (calls) / Large (puts) | Strike price - premium |
Key Options Terminology
| Term | Definition |
|---|---|
| Strike Price | Price at which option can be exercised |
| Premium | Price paid to buy the option contract |
| Expiration | Date when option contract expires |
| In-the-Money (ITM) | Option has intrinsic value |
| At-the-Money (ATM) | Strike ≈ current price |
| Out-of-the-Money (OTM) | Option has no intrinsic value |
| Intrinsic Value | Difference between strike and market price |
| Time Value | Premium - Intrinsic value (decays over time) |
| Exercise | Using your right to buy/sell |
| Assignment | Being obligated to fulfill the contract |
How Options Pricing Works
Option Premium = Intrinsic Value + Time Value
Example:
Stock Price: $150
Call Strike: $145
Premium: $8
Intrinsic Value: $150 - $145 = $5 (in-the-money)
Time Value: $8 - $5 = $3 (time until expiry)
What Affects Premium:
| Factor | Calls | Puts |
|---|---|---|
| Stock price rises | Premium ↑ | Premium ↓ |
| Stock price falls | Premium ↓ | Premium ↑ |
| More time to expiry | Premium ↑ | Premium ↑ |
| Higher volatility | Premium ↑ | Premium ↑ |
| Higher interest rates | Premium ↑ | Premium ↓ |
The Greeks (Brief Overview)
| Greek | Measures | Practical Meaning |
|---|---|---|
| Delta | Price sensitivity | How much option moves per $1 stock move |
| Gamma | Delta change rate | How fast delta changes |
| Theta | Time decay | How much value lost per day |
| Vega | Volatility sensitivity | Impact of volatility change |
| Rho | Interest rate sensitivity | Impact of rate changes |
Delta Guide:
- ATM Call: ~0.50 delta (moves $0.50 per $1 stock move)
- Deep ITM Call: ~0.90-1.00 delta (moves almost like stock)
- OTM Call: ~0.10-0.30 delta (small movement)
Basic Options Strategies
1. Long Call (Bullish)
- Buy a call option
- Profit: Unlimited upside potential
- Risk: Limited to premium paid
- Best when: Expecting strong upward move
2. Long Put (Bearish)
- Buy a put option
- Profit: Large downside potential (to zero)
- Risk: Limited to premium paid
- Best when: Expecting strong downward move
3. Covered Call (Income)
- Own stock + sell call against it
- Profit: Premium received + stock appreciation to strike
- Risk: Stock decline (offset by premium)
- Best when: Neutral to slightly bullish
4. Protective Put (Insurance)
- Own stock + buy put for protection
- Profit: Unlimited upside, protected downside
- Risk: Premium cost reduces returns
- Best when: Want downside protection
Options vs. Stock/Forex Trading
| Factor | Options | Stock/Forex |
|---|---|---|
| Risk | Defined (buyers) | Can be large |
| Leverage | Built-in | Margin required |
| Time | Works for/against you | Neutral |
